If any of you are having problems such as when you play games, your monitor and everything is turned ON but the screen turns black and says “No Signal”, I think i found a solution about solving the problem…
I had the same proble mand fixed it SUDDENLY! 😀
All you need to do is go to BIOS. You can go to BIOS after you turn on your computer… You will see hotkeys in the screen for them.. Boot menu and BIOS.
Boot menu is F12. To mine BIOS is F2…. its normally F2 or Delete button.
Ok after clicking the hotkey for BIOS, click the advanced chipset settings. Then, click the AGP thing… i forgot… but.. change it exactly as how much memory ur PC memory is.. or your new graphics card memory. Mine, my old one used to be 128mb, my new graphics card was 512mb and thats why it didnt work, it was set to 128, so i changed to 512 😀
